General Aviation Portable Hydraulic Test Stand

The General Aviation Portable Hydraulic Test Stand from Hydraulics International, Inc. (HII) is a compact, reliable, and efficient hydraulic servicing solution specifically engineered for general aviation aircraft. The stand offers superior portability and ease-of-use, making it particularly valuable in smaller aviation operations, regional airports, flight schools, and maintenance facilities focused on general aviation aircraft.

This portable hydraulic test stand is designed to deliver consistent hydraulic power necessary to test, troubleshoot, service, and maintain hydraulic systems found on a broad range of small to medium-sized aircraft. It provides adjustable flow rates and pressures tailored to accommodate varying system requirements, typically delivering flows ranging from 5 to 15 gallons per minute (GPM) at pressures up to 3000 pounds per square inch (PSI). This allows precise simulation of actual operating conditions, essential in validating hydraulic component integrity and system reliability.

An integral feature of the stand is its electric motor-driven or gasoline-engine-driven design, chosen according to customer needs or environmental requirements. Electric motor-driven models offer quieter, emission-free operation suitable for enclosed environments, while gasoline-engine-driven units provide maximum portability and independence from electrical infrastructure, ideal for outdoor, remote, or field maintenance tasks.

The equipment includes an advanced hydraulic fluid filtration system, typically employing high-pressure filtration rated at approximately 3 microns and a low-pressure return filter of around 25 microns. These high-quality filters protect aircraft hydraulic components by maintaining hydraulic fluid cleanliness at the highest aviation standards. Continuous filtration protects sensitive aircraft hydraulic systems from contaminants, reducing component wear and prolonging service life.

A stainless-steel hydraulic reservoir, generally between 20 to 60 liters in capacity, provides sufficient fluid storage for extensive maintenance operations. The reservoir design incorporates convenient inspection and servicing features such as visual level indicators, temperature monitoring, and quick-fill/drain ports for ease of operation and rapid turnaround.

Equipped with comprehensive instrumentation, the stand offers digital or analog gauges for accurate monitoring of hydraulic pressure, fluid flow rate, and temperature. Diagnostic indicators, such as contamination monitors, assist operators in quickly identifying fluid-quality issues, facilitating immediate corrective action.

The rugged, lightweight design of the test stand is optimized for portability. It includes durable wheels, convenient handles, and compact dimensions, enabling effortless movement within hangar spaces, flight lines, and outdoor operational environments.

Applications of this test stand encompass a wide range of maintenance tasks critical to general aviation. It supports routine preventive maintenance checks, hydraulic system troubleshooting, component functional verification, and hydraulic fluid flushing and replacement procedures. Additionally, it's an essential tool for aircraft maintenance training programs, providing technicians and students hands-on experience in hydraulic system servicing.

By using the General Aviation Portable Hydraulic Test Stand, aircraft owners and operators ensure hydraulic system reliability, safety, and compliance with aviation regulatory standards, thus minimizing downtime and maintenance costs.
